Areas of Practice

TAx controversy & litigation

Interacting with the the Internal Revenue Service ("IRS"), the Alcohol and Tobacco Tax and Trade Bureau ("TTB"), the U.S. Department of Justice - Tax Division, and the various state taxation authorities, can be highly contentious and intimidating for the uninitiated.  Whether during an audit/investigation, administrative proceedings, trial, or on appeal, Mr. DiRuzzo delivers extraordinary results to his clients.

White collar criminal defense

White collar criminal defense requires knowledge of substantive criminal law and criminal procedure, experience at trial and on appeal, and the understanding of the environment which businesses operate.  Having tried over 40 criminal cases to verdict in federal, state, and territorial courts, and bringing his background as both a Board Certified Specialist in Criminal Appellate Law and as a CPA, Mr. DiRuzzo can represent anyone accused of committing a white collar crime at every stage of the case - government/grand jury investigation, trial, and appeal.

So many problems can be avoided with advanced tax planning.  Whether it is structuring a transaction, or reviewing the documentation with a view to a potential audit, Mr. DiRuzzo assists business and individuals minimize the risk that is present in every tax planning transaction.

virgin Islands & territorial taxation

The United States Virgin Islands and the American Territories and Possessions are unique for tax law and tax litigation because they are not states, which raises highly complex issues of taxation. Mr. DiRuzzo regularly litigates against the Virgin Islands Bureau of Internal Revenue, having secured tax refunds for his clients in the tens of millions of dollars.                     

complex civil & Governmental litigation

When numbers and accounting are the focus of the case, most attorneys are out of their comfort zone.  Having a background as a CPA with an advanced degree in accounting, Mr. DiRuzzo is able to make sense of accounting, tax, and financial issues that are central to high-stakes civil litigation, delivering results to his clients in a cost-effective manner.  Additionally, Mr. DiRuzzo has experience litigating against the alphabet soup of governmental agencies (e.g., FTC, FDA, DOJ) for individuals and businesses that have become adverse to the government.
